What the heck is happening to GA and RA???

As a tank main (All the champs I play are tanks minus graves) I have mixed feelings about the pbe updates. I really like what abyssal, banshees, and (especially nice for me because I am a zac main). I think most of the changes are pretty good (although the 425 health thing is a little weird). And the new items seem nice. Except for 2. GA and RA. Starting with GA, it is a really good item if you are behind, or could use the resistances it gives you, plus, that passive is really nice. Now 40 AD 30 Armor. This takes it away from any AP champions, which sucks, cause I love running this item on zac, and when I play mid lane, I like picking it up on zilean. But now, you completely remove MR from it and add ad. That is confusing to me. If you want, why not have 2 seperate items, one which does this and one with similar, or tuned old GA. That would be nice. Then RA, just like the entire community is saying, make even more annoying and it is pretty awkward to remove crit reduction. I wanted to focus more on the GA, because a lot has been said by others about RA. But still, both changes are weird, and wouldn't really help tanks. (Now realizing that randuins is my second item on zac and starting to get annoyed.) I really dislike both changes and I hope these dont make it to live. Whatever though the game goes on.

Sorry if this sounds disorganized, I was pretty tired while writing this.
